Description:
Use your solderless breadboard and wire jumpers to make these connections:
| LCD Pin | Connect to |
| 1 (VSS) | GND pin* |
| 2 (VDD) | + 5v pin |
| 3 (contrast) | Resistor or potentiometer to GND pin* |
| 4 RS | pin 12 |
| 5 R/W | pin 11 |
| 6 Enable | pin 10 |
| 7 No connection |
|
| 8 No connection |
|
| 9 No connection |
|
| 10 No connection |
|
| 11 (Data 4) | pin 5 |
| 12 (Data 5) | pin 4 |
| 13 (Data 6) | pin 3 |
| 14 (Data 7) | pin 2 |
| 15 Backlight + | Resistor to pin 13** |
| 16 Backlight GND | GND pin* |
*Use a breadboard rail to make multiple connections to the GND pin for Arduino
*For potentiometer connection, use the potentiometer's center pin and either of the other pins to make the connection from LCD pin 3 to Arduino GND
** A current limiting resistor or potentiometer (40 Ohm minimum) should be used to avoid excessive current. It should look something like this:
Software
Here is the driver code:/* ------------------------------------------------------------------------------- */
// character LCD example code
// www.hacktronics.com
#include <LiquidCrystal.h>
// Connections:
// rs (LCD pin 4) to Arduino pin 12
// rw (LCD pin 5) to Arduino pin 11
// enable (LCD pin 6) to Arduino pin 10
// LCD pin 15 to Arduino pin 13
// LCD pins d4, d5, d6, d7 to Arduino pins 5, 4, 3, 2
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);
int backLight = 13; // pin 13 will control the backlight
void setup()
{
pinMode(backLight, OUTPUT);
digitalWrite(backLight, HIGH); // turn backlight on. Replace 'HIGH' with 'LOW' to turn it off.
lcd.begin(20,4); // columns, rows. use 16,2 for a 16x2 LCD, etc.
lcd.clear(); // start with a blank screen
lcd.setCursor(0,0); // set cursor to column 0, row 0 (the first row)
lcd.print("Hello, World"); // change this text to whatever you like. keep it clean.
lcd.setCursor(0,1); // set cursor to column 0, row 1
lcd.print("keyes");
// if you have a 4 row LCD, uncomment these lines to write to the bottom rows
// and change the lcd.begin() statement above.
//lcd.setCursor(0,2); // set cursor to column 0, row 2
//lcd.print("Row 3");
//lcd.setCursor(0,3); // set cursor to column 0, row 3
//lcd.print("Row 4");
}
void loop()
{
}

You will now have a folder called LCD_example
Start the Arduino software and load the example program by clicking File->Sketchbook->Open
Navigate to the LCD_example folder and select the ?LCD_example.pde? file.
Transfer the program to your Arduino by clicking the ?Upload to I/O board? button. After uploading, on the LCD you should see:
